Grain Pattern

Straight grain with a mix of cathedral and quarter-sawn patterns typical of hewn or boxed-heart structural timbers, showing prominent medullary rays.

Color & Appearance

Medium to light brown with grayish undertones on the weathered exterior surfaces; freshly exposed interior heartwood is typically a richer golden-brown.

Hardness (Janka)

1360 lbf (Hard)

Durability & Decay Resistance

Very Durable

Value & Sustainability

Estimated Market Value
$6.00 to $12.00+ per board foot (higher for premium reclaimed old-growth structural timbers)
Wood Age Estimate
Estimated at 80 to 120+ years old based on the heavy patina, checking, oxidation, and structural timber format typical of historical construction.
Sustainability Status
Abundant and not CITES-listed; highly sustainable when salvaged and repurposed as reclaimed timber.

Common Uses

Heavy timber framing, structural beams, reclaimed wood furniture, flooring, boat building, and exterior applications.

Geographic Origin

Eastern North America

Workability

Moderate to difficult due to density and hardness, especially when dry. Prone to splitting with nails, so pre-drilling is recommended. Accepts glues and finishes well.

Finish Recommendations

Penetrating oils, hardwax oils, or polyurethane. For reclaimed timbers, light wire brushing followed by a natural matte finish preserves the authentic rustic patina.

Notable Features

Closed cellular structure (tyloses) making it naturally water-resistant and rot-resistant, high tannin content, prominent ray fleck patterns.
